HEATING-STOVE.

SPECIFICATION formingpart Of Letters Patent NO. 706,097, dated August 5,1902. Application filecl March 6,1902. Serial No. 96,981. (No model.)

ing to so construct a stove of this chara'c-' ter that it will radiatethe greatest possible amount of heat by the expenditure of acomparatively small quantityof fuel andconsume practically all of thefuel and. at the same time provide a neat and attractive freeburningstove; and with this object in viewthe invention consists in certainnovel features of construction and combinations and arrangements ofparts, as will be more fully hereinafter described, and pointed out inthe claims In the accompanying drawings, Figure 1 is aview in section,illustrating my improvements; and Fig. 2 is a view in section on theline a: a; of Fig. 1.

1 represents the stove-body, preferably supported on feet 2 and dividedinto the combustion-chamber 3 and ash-pit 4, a fuel-door 5 be-' ingprovided for the former and-a door 6 for the latter to permit theremoval of ashes and to regulate the draft.

On top of the stove-body 1 and forming a permanent part of the stovenay-improved heating-drum is located and consists of an:

inverted truncated cone '7, communicating with a central opening in thetop of'body l and forming a large heat-radiating surface inclosed in aperforated casing 8 to permit the free circulation of air about saidradiating surface, and the top 9 of the drum is made solid and projectsthe desired distance above cone 7 and forms, together with casing 8, aninclosure for the cone.

The smoke-pipe 10 projects down through this top 9 and has secured toits lower end and spaced therefroman inverted'cone 11, metal straps orstrips 12 being employed to connect the cone 11 and pipe 10 and permitthe smoke and gases to freely enter the pipe. The cone 11 is appreciablysmaller than cone 7 to provide a'smoke-passage between said cones, theformer serving to deflect the smoke and gases against the latter toinsure the intensely heating of cone 7 and'permit the same to radiate alarge amount of heat.

In order to insure the burning of practically all smoke and gases, areturning-flue 13 connects the pipe 10 with ash-pit 4, and a damper 14is provided in pipe 10 above its connection with flue 13 to regulate thequantity of return to produce the best results. This damper 14 ispreferably perforated, as shown, to prevent the draft through the pipefrom being entirely out off, as some draft through pipe 10 is alwaysadvisable.

In operation the smoke and gases pass up between cones 11 and 7,intensely heating the latter, and as air finds a free entrance andescape through perforated casing 8 a great amount of heat is therebyimparted to the air. The smoke and gases find their way aroundand downinto cone 11, as indicated by the arrows, and escape through pipe 10, aportion of the same being drawn down through flue 13 to ash-pit 4, whereit mixes with fresh air entering through door 6 and again passes throughthe combustion-chamber to be entirely consumed.

' Slight changes might be resorted to in the general form andarrangement of the several parts described without departing from myinvention, and hence I would have it understood that I do not limitmyself to the precise details set forth, but consider myself at libertyto make such slight changes and alterations as fairly fall within thespirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a stove, the combination with acombustion-chamber and an ash-pit below the same, of an inverted conecommunicating with the upper end of the combustion-chamber, a casinginclosing the cone and perforated around said cone, a smoke-pipeprojecting through the top of the casing and an inverted cone connectedwith and spaced from the pipe and adapted to deflect the smoke and gasesagainst the first-mentioned cone before they enter the pipe.

2. In a stove, the combination with a com- IOC smoke-passage betweenthem, a casing inclosin g the cones and perforated around the outercone, a smoke-pipe communicating with the casing and projecting downinto the inner cone, a flue connecting the smoke-pipe and ash-pit, and adamper in said smoke-pipe above its connection with the flue.

In testimony whereof I have signed this specification in the' presenceof two subscribing witnesses.
